Abstract
A cell monitoring device for monitoring cells connected in series in an electric storage module includes electric lines, switches connected in parallel to the cells, respectively, via the electric lines, and a controller. The controller configured to: close and reopen at least two of the switches; measure voltages between the lines connected to the cells after the switches connected in parallel to the cells are reopened; determine the measured voltages as cell voltages of the cells; determine whether at least one of a high abnormality voltage equal to or higher than a first threshold and a low abnormality voltage equal to or lower than a second threshold lower than the first threshold exists among the cell voltages; and determine at least one of the electric lines has lost continuity if at least one of the high abnormality voltage and the low abnormality voltage exists among the cell voltages.
